One step simpler would be to put each of the field names into an array and then loop through using your code above:
$my_fields = array('position','dimension','color','weight','etc');
foreach ( $my_fields as $my_field ) {
if ( the_field( $my_field ) ) echo the_field( $my_field );
}
If you want to go one step more complicated, you could try automatically building the array of field names by querying all the fields within a particular field group.
